摘要
以氨氮的硝化为目的 ,对浮动床生物膜硝化反应器采用具有表面积大 ,不易堵塞的新型载体填装进行试验。研究表明 :在碱度过剩且不存在有机负荷的条件下 ,硝化反应速率或是由氧的浓度决定或是由氨氮的浓度决定。当氧的浓度为硝化反应限速因素时 ,氧的浓度对硝化反应速率有很大影响 ,当氧的浓度达到 4 .5 mg/ l时 ,硝化反应速率可达到 2 4 0 g NOx- N/ m3·
A new biofilm reactor moving bed reactor which is filled with carriers bearing high specific surface and less possibilities of clogging is studied.The experiment results show that when alkalinity is in excess and there is no organic load, the nitrification rate can be determined either by the ammonium concentration or by the oxygen concentration.We have found that the oxygen concentration imposes a great influence on the nitrification rate when oxygen becomes a rate limiting factor.When the oxygen concentration is about 4.5mg/l, the nitrification rate can reach at 240gNOx N/m 3·d.
